5.FAQ

We have organized several common questions for our clients，may help you sincerely：

①What’s the Application for the products?

Flexible Duct is widely used in Heating, Cooling, and Air Conditioning (HVAC) systems for air ventilation applications. Flexible Duct provides greater thermal efficiency to save energy. Because it is flexible,it is easy to run around and through obstacles in the building.

② What’s the Advantages for the products?

No need special tools for cutting

In case of fire no toxic gas are emitted

The product have been successfully tested for fire resistance

Can be bent in any direction

③ What's the construction?

2 layers of the aluminium laminated with the polyester with the coil made of the spring wire.

Total 3 layers:

——1st layer: Aluminum foil ( 10um)

——2nd layer: Polyester(15um)

——3rd layer: PVC ( 15um)

spring wire: carbon steel from 0.9~1.3mm

Q: Air to water heater host and air conditioning host is not the same: This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.

Q: US direct mail dysonhp01 Dyson air purification cooling machine triple in the country to warranty it: Among them, the extruded polystyrene gypsum composite board is based on paper gypsum substrate, the use of adhesive and extruded polystyrene board through the factory processing compound

Q: Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter: Not the ,,, mobile air conditioning inside the compressor, the winter heating also need the compressor, but also a ventilation pipe, charged heating Well?

Q: I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More: The general level of more than 12 layers when you need to use.

Q: Air conditioning machine work when the sound is too much reason: Color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of organic coating with steel plate

Q: What is the whole heat exchange fresh air ventilator?: Second, the new insulation decorative board is integrated through the production line, set insulation, waterproof, finishes and other functions in one, is to meet the current housing construction energy needs, improve the industrial and civil building exterior wall insulation level of the preferred material, but also on the existing Building energy-saving transformation of the preferred materials

Q: External wall insulation method of operation There are several combinations of materials: Seeking the existing building construction specifications Daquan! The The @

Q: Ventilation is very good, why still have to install fresh air system: You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%

Q: In the design, the building structure and the hydropower are generally designed by the Architectural Design Institute. The air conditioning ventilation is based on the design of the room. Or first air conditioning ventilation? More: Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,

Q: HVAC Heating: What are the main components of the air distribution system?: Geothermal construction, the heating pipe spacing can not be less than 100mm, the construction can not be achieved, big brother!
